Gravity beneficiation process flow of tungsten iron ore

Tungsten iron ore is an important metallic mineral with extensive applications in industrial production. In order to improve the grade and recovery rate of tungsten iron ore, gravity beneficiation process is needed for beneficiation. This article will introduce the gravity beneficiation process of tungsten iron ore, helping readers better understand and master beneficiation technology.

1、 Gravity beneficiation principle of tungsten iron ore

Gravity beneficiation of tungsten iron ore is a process that utilizes the different settling velocities of minerals in the gravity field and separates them through gravity beneficiation equipment. There is a significant difference in the specific gravity of tungsten and iron minerals in wolframite, which can be separated by gravity beneficiation equipment to improve the grade and recovery rate of wolframite.

2、 Gravity beneficiation process flow of tungsten iron ore

1. Crushing and screening

After crushing and screening of tungsten iron ore, large pieces of ore are decomposed into small pieces for convenient subsequent beneficiation treatment. Usually, cone crushers and vibrating screens are used for crushing and screening.

2. Grinding

After crushing and screening, the ore needs to be ground. Grinding can refine the ore and increase its surface area, which is beneficial for beneficiation. Usually, ball mills are used for grinding treatment.

3. Reselection

Gravity beneficiation is the core process of tungsten iron ore gravity beneficiation. The gravity separation equipment includes spiral sorting machines, traditional Chinese medicine pumps, flotation machines, etc. During the gravity separation process, the ore undergoes different gravity fields to separate minerals of different densities, thereby improving the grade and recovery rate of wolframite.

4. Magnetic separation

Magnetic separation is an important part of tungsten iron ore beneficiation. Magnetic separation can remove magnetic impurities from ores, improve the grade and recovery rate of tungsten iron ore. Magnetic separation equipment includes magnetic separators, magnetic separation plates, etc.

5. Flotation

Flotation is a commonly used mineral processing method that can improve the grade and recovery rate of tungsten iron ore. Flotation equipment includes flotation machines, air flotation separators, etc. During the flotation process, the ore is treated with chemical agents, causing bubbles to form on the surface of the mineral, allowing it to float on the water surface and achieve separation.

Advantages and disadvantages of gravity beneficiation process for tungsten iron ore

The gravity beneficiation process of tungsten iron ore has the following advantages:

1. The beneficiation effect is good. Gravity beneficiation equipment can separate according to the density difference of minerals, which can effectively improve the grade and recovery of wolframite.

2. The process flow is simple. The gravity beneficiation process for tungsten iron ore is relatively simple and does not require complex equipment and processes.

3. Low investment cost. Compared to other beneficiation processes, the investment cost of tungsten iron ore gravity beneficiation process is lower.

The disadvantages of the gravity beneficiation process for tungsten iron ore are:

1. Mineral processing equipment is prone to wear and tear. Gravity beneficiation equipment wears out quickly and needs to be replaced regularly.

2. A large amount of waste residue is generated during the beneficiation process. During the gravity beneficiation process, a large amount of waste residue is generated and needs to be treated and disposed of.

4、 Conclusion

The gravity beneficiation process of tungsten iron ore is a commonly used beneficiation method, which has the advantages of good beneficiation effect, simple process flow, and low investment cost. During the beneficiation process, attention should be paid to the wear and tear of beneficiation equipment and the treatment of waste residue. I hope this article can help readers better understand and master the gravity beneficiation process of tungsten iron ore.
